Krytox™ GB (Gearboxes) Performance Lubricants

Lubricants to Enhance Performance and Extend the Life of Gearboxes

Krytox™ high-performance lubricants are designed to protect high-temperature gearbox gears, bearings, and seals. Krytox™ fluoropolymer greases will not oxidize, even in applications with operating temperatures up to approximately 270 °C (518 °F).

Krytox™ gearbox greases and oils help eliminate bearing and gear failures resulting from lubricant oxidation, which leads to extended seal and gearbox life. In many applications, Krytox™ gearbox lubricants last the life of the gearbox, greatly reducing or eliminating the need for maintenance and relubrication.

Features and Benefits of Krytox™ Performance Lubricants for Gearboxes

Krytox™ performance lubricants are formed from a perfluoropolyether- (PFPE-) based polymer composed of fluorine, oxygen, and carbon. No hydrogen is present in the molecule, resulting in exceptional properties that make these lubricants:

  • Nonreactive
  • Nonflammable
  • Safe in harsh environments
  • Long-lasting
  • Compatible with all seal materials

A Range of Product Grades to Fit Every Application

Krytox™ performance lubricants for gearboxes are available in various base oil viscosities to provide the best performance for a given environment.

Two grades of premium performance gearbox grease, Krytox™ GB M0 and Krytox™ GB H0, are semi-fluid lubricants specifically designed for enclosed gearbox lubrication. Many gearbox designs use bearings that are not lubricated by the internal lubricant reservoir and require periodic relubrication. For these gearboxes, two other premium grades—Krytox™ GB A2 and Krytox™ GB C2—limit cross-contamination of the internal grease with a non-compatible bearing grease.

There are also three oils with differing viscosities for gearbox applications. See the complete line and associated properties in the tables below.
